In my mother country, which is not the U.S., I had good relationships with many people. Although I was a little shy, it didn't affect my social life much. After I moved to the U.S. three years ago, however, I began to change mentally. Unlike many foreigners who learn English very quickly, my English level has been remaining almost the same. I naturally became very quiet and didn't pay attention during class. As my sociability decreased, I couldn't make eye contacts with anyone anymore and my whole body, especially my neck muscles, became stiff like rock when I tried to. My every single movement becomes very clumsy from that point until everyone around me is gone. What's worse, when others saw me and knew I was uncomfortable to be with anyone, they couldn't make eye contacts with me either. Their muscles become stiff as well, and they move very awkwardly as if they couldn't control them, almost like they were having a seizure.
I tried to act like normal people everyday but kept failing. My social life is now worse than that of anyone I know. It's also aggravating my depression more and more.
This is not all, but I can't explain more deeply because of my poor English. I thought I was suffering from social anxiety disorder, but it seems to be more than that. Does anyone have a clue about what it is?
